WILLIAM A. MARTIN, OF FORT WORTH, TEXAS.

OULTIVATOR.

Application filed September Hy invention relates to cultivators and more particularly to a rotating cultivator for stirring and scarifying the surface of the earth or land; and the object is to provide attachments which can be attached to a variety of wheeled vehicles or carriers which can be used for cultivating and thinning different kinds of crops, such as cotton. corn, milo maize, sorghum, sugar beets,'and other young plants which require thinning and thorough Working, and to provide means for manual control of the operating devices. Other objects and advantages will be fully explained in the following description. and the invention will be more particularly pointed outin the claims.

Reference is had to the accompanying drawings which form a part of this application.

F ig. 1 is a side elevation of the improved cultivating devices, showing sufficient parts of a wheeled carrier for illustrating the improvements.

Fig. 2 is a plan view of the operating devices.

Fig. 3 is a perspective View of one of the scarifiers, showing the manner of mounting and adjusting the same.

Fig. 4 is a detail view of one of the cultivators shown in section.

Fig. 5 is a detail sectional view, showing the'construction of the devices for mounting the rotary spindle.

Similar characters of reference are used to indicate the same parts throughout the several views.

The drawings show a wheel 1 and a portion 2 of a cultivator frame which is connected to the axle of the cultivator. The cultivator is provided with a vertically adjustable standard and draft beams opera- The cultivator standard 3 has a rack 4, sector gear 5, lever 6, and connecting parts. A pair of traction members or draw beams '7 are at tached to the standard 3, one member on each side thereof. A seat 8 is attached to the frame 2.

The operating mechanism includes a circular frame having inner member 9 and outer member 10. The members 9 and 10 are spaced apart by blocks 11 and bolts 12 secure the blocks 11 in place and secure the members 9 and 10 in their spaced relation. Means are provided for suspending the oper- 4, 1925. Serial No. 54,393.

ating frame. A circular bearing disk 13' and bars 14 are attached to the frame. The bars 14 are preferably angle bars. A spindle bolt 15' is secured to the plate 13. A sleeve 16 is mounted on the plate 13 about the spindle 15 and secured thereon by a bracket 17 and nut 18. A brace 19 consisting of members 20 and 21 is rigidly connected to the bracket 17 and at the upper end the brace connected to the vertically adjustable plcw standard 3 which serves as a support for the brace 19. An arm 20 is rigidly clamped on the sleeve 16 and this arm 20 is pivotally connected to the draft beams 7 When the standard 3 is adjusted vertically, the working frame 9-10 will be adjusted also.

Means are provided for the horizontal ady. ment of the frame 91O when assembling the cultivator. A segment rack 21 is attached to thedraft beams 7 and a lever 22, provided with a spring-actuated dog, is fulcrumed on the beam 7. An upstanding lug 23 is attached to the arm 20. The lever 22 is pivotally connected to the lug 23. The

standard 3, beams 7 brace 19, sleeve 16, bar 20 and the cultivator frame are all elevated and maintained at any desired position by the lever 6.

Disk plows 24 are attached to the working frame, as shown in Fig. 4. Spindles 25 are rigidly connected to the plows 24 and then hung on the operating frame 91O rigidly therewith by means of the plates 28, nut 27, and sleeve 26. There may be as many of the disk plows 24 as may be required. The cen tral disk 24 is connected by similar means to a bracket 29, which is connected to the plate 13 and arms 14. The frame 9-10 is thus rotatably mounted and the disk plows 24 will do their work when the plor. drawn across the field. The plows 24 will never become choked because the frame 9-10 will yield and let the slow which becomes clogged turned to the rear so that whatever is hung on the disk will be thrown off.

Fig. 3 illustrates plowing implements which may be substituted for the disks 24.

The scarifiers are attached to the frame 9-10 by a plate 31 which is perforated near the ends to receive the scarifiers 30 which are hung on the frame. The plate 31 is hung on the frame by a hooked bolt 32 and a nut 33 is screwed on the lower end of the bolt 32 to clamp the plate 31 against the frame and to pull the Jend of the arms 30 down on the frame 9 10.

That I ch in], is

1. In a cultivator provided with a plow standard and draft beams attached thereto and supported thereby and extending rearvrardly therefrom; a rotatable spindle and a bearing therefor supported by said beams, a circular carrying t'raine carried by said spindle and autonmtically rotatable in either direction, a brace bar operatively connected With said standard and said spindle bearing, and cultivating devices carried by said lran'ie.

In a cultivator provided with a standard and dral t beams attached thereto and supported thereby and extendingrearvardly therefrom; a verti -ally disposed spindle and a bearing therefor supported by said beams, abracc bar op ratively connected to said standard and to said b aring and co-operating with said Beams to support the same, a horhontally disgo" circular carrying t aine carried by said spindle and automatically rotatable in either direction by the Work to be done, and caltivating devices carried by said tr.

3. In a cultivator provided with a plow standard and draft beams attached thereto and supported thereby and exendine' rearvardly therefrom, a vertically disposed spindle, a bearing for said spindle supported at its upper end from said standard and supported at its lOWGl' end by said bea-ins,

l i L :1 circular horizontally disposed carrying frame carried by said spindle automatically rotatable in either direction, and culti 'ating devices carried by said frame.

In a cultivator provided with a plow 1rd and d aft beams attached thered supported thereby and extending rdly therefrom, a vertically disposed a bearing for supporting said spinb ace attached to said standard and .=d with a bracket for supporting said means carried by said beams for the lower end of said bearing,

disposed automaticalhorizontal J ue carrying t'rame carried by said 10, and cultivating devices carried by frame.

) In a cultivator p 'ovided with t. plow 1d and draft beams attached theresupported thereby and extending tly theretronr a v rtically disposed a bearing for said spindle, a brace c 1 to said standard and provided with a bracket for supporting said bearing at its uiper e id, adjustable means for supporting the lower our of said bearine from said beams; a circular horizontally disposed aurotatable carrying f anie ope ato said spindle, and cultts carried by said frame.

ony whereof, I set my hand, this August, 1925.
